instances

I was wondering about the best practices in synchronizing multiple azure instances that run the same role. More precisely, I want to prevent several worker roles to work on the same work-unit. Azure queues do not seem to help on this matter. One option is to use an sql table with locks and stored procedures; but using sql synchronization in Azure seems a bit awkward. Any ideas? Edit, my detailed(but simplified problem) is as follows: There are n targets. A unit of work must be done on each target at a specified interval (say 30 seconds - but it is different for each target). I have m workers

Using the topic Overview - Handle Enumeration , number 5, the attempt Close mutex of another process and and information from Mutex analysis, the canary in the coal mine and discovering new families of malware/ , I have came up with: Attempt 1: http://pastebin.com/QU0WBgE5 You must open Notepad first. Needless to say, this is not working for me. I need better error checking to figure out what's going on. I don't know how to get mutex pointers in the format I see them in Process Explorer . My goal is to be able to delete/kill of the mutex handles created by a process so more than one instance

I am reading introduction to Scala paper and found following statement: It should be noted that some object-oriented languages do not have the concept of class. Question: Which object-oriented languages do not have class concept and how do they handle type(class) - object(type instance) relationship ? Although it is common in popular languages to conflate them, classes and types are different concepts. A class is properly understood as a blueprint for an object, defining the attributes and methods that instances of the class possess, but an (object) type is an interface, describing what

I need a class that works like this: >>> a=Foo() >>> b=Foo() >>> c=Foo() >>> c.i 3 Here is my try: class Foo(object): i = 0 def __init__(self): Foo.i += 1 It works as required, but I wonder if there is a more pythonic way to do it. Nope. That's pretty good. From The Zen of Python: "Simple is better than complex." That works fine and is clear on what you're doing, don't complicate it. Maybe name it counter or something, but other than that you're good to go as far as pythonic goes. Abuse of decorators and metaclasses. def counting(cls): class MetaClass(getattr(cls, '__class__', type)): _

I have Tomcat 6.0 installation on my Win7 PC. I used 64/32bit windows installation. In Eclipse I was able to set paths and set server to use my Tomcat installation. Everything seems working fine until I run server from inside Eclipse. I noticed that http://localhost:8080/index.html page is not available (Tomcat default home page). I also can't access http://localhost:8080/axis2 . I have Axis2 installed too. Since I am struggling to make simple axix2 web service for long time, I am thinking maybe this Eclipse instance of Tomcat is adding to my issues? When I start Tomcat from windows GUI

I want to instantiate objects in XAML, and reuse these instances. I think it should be simple but I'm stuck, I'm probably missing something obvious. Say I want to add Cats to different Rooms (Room has an ObservableCollection containing objects of type Cat). In the UserControl.Resources I create ObjectDataProviders: <ObjectDataProvider x:Key="Cat1" ObjectType="{x:Type local:Cat}"> <ObjectDataProvider.ConstructorParameters> <System:String>Tom</System:String> </ObjectDataProvider.ConstructorParameters> </ObjectDataProvider> <ObjectDataProvider x:Key="Cat2" ObjectType="{x:Type local:Cat}">
